Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 1, the present embodiment comprises: staking screw rod 1, collar 2, adapter sleeve 3, ball 4, overcoat 5, elastic spring 6, pull bar 7 and opposite side face 8, wherein adapter sleeve 3 two ends are connected to the pull bar 7 on staking screw rod 1 and nut riveting tool, and overcoat 5 is arranged on adapter sleeve 3.
Described staking screw rod 1 two ends are provided with external screw thread, and the termination, one end be connected with adapter sleeve 3 is provided with the opposite side face 8 as chocking construction, and opposite side face 8 is the plane matched with ball 4.One end outer wall that adapter sleeve 3 is connected with staking screw rod is provided with annular groove, is provided with collar 2 in annular groove.The outer wall of adapter sleeve 3 is provided with elastic spring 6, and overcoat 5, under the effect of elastic spring 6 and collar 2, is in fixed position time static, and can axially slides.Adapter sleeve 3 is provided with two holes with the radial direction of opposite side face 8 correspondence position, in order to place ball 4.Overcoat 5 inwall is provided with two grooves, and when overcoat 5 slide rearwardly to certain position, two grooves are relative with the hole of two on adapter sleeve 3.
Described staking screw rod 1 is by being threaded in adapter sleeve 3, and sliding outer cover 5, makes overcoat 5 inboard wall groove relative with two holes of adapter sleeve 3.When two holes on the opposite side face 8 on staking screw rod 1 with adapter sleeve 3 just pair time, overcoat 5 moves to initial position along direction shown in Fig. 1 upper arrow under the effect of elastic spring 6, the ball 4 be arranged in through hole contacts with opposite side face 8 under the effect of overcoat 5 inwall, as staking screw rod 1 upper spheres 4 in Fig. 2, the radial motion of overcoat 4 inwall restriction ball 4, thus make staking screw rod 1 can synchronous rotary with adapter sleeve 3.
Described staking screw rod 1 needs with when changing, as shown in Figure 1, in figure, overcoat 5 is moved in adapter sleeve 3 lower arrow direction, make the groove of overcoat 5 inwall relative with two holes of adapter sleeve 3, lower spheres 4 as shown in Figure 2 falls into groove, like this, staking screw rod 1 can rotate relatively with adapter sleeve 3, thus unloads staking screw rod 1.
This device is compared with prior art, simple to operate, and structure is convenient and reliable, and volume compact is small and exquisite, and processing cost is low.
Embodiment 2
The present embodiment difference compared with embodiment 1 is:
As shown in Figure 3, the chocking construction matched with the ball 4 in adapter sleeve 3 in embodiment 1 is opposite side face 8, and the chocking construction in embodiment 2 is two circular troughs 9 be arranged on staking screw rod 1, circular trough 9 matches with ball 4, makes staking screw rod 1 and adapter sleeve 3 geo-stationary in a rotational direction.
Described staking screw rod 1 is by being threaded in adapter sleeve 3, and sliding outer cover 5, makes overcoat 5 inboard wall groove relative with two holes of adapter sleeve 3.When two holes on the circular trough 9 on staking screw rod 1 with adapter sleeve 3 just pair time, overcoat 5 moves to initial position along direction shown in Fig. 3 upper arrow under the effect of elastic spring 6, the ball 4 be arranged in through hole contacts with circular trough 9 under the effect of overcoat 5 inwall, as staking screw rod 1 upper spheres 4 in Fig. 4, the radial motion of overcoat 4 inwall restriction ball 4, thus make staking screw rod 1 can synchronous rotary with adapter sleeve 3.
Described staking screw rod 1 needs with when changing, as shown in Figure 3, in figure, overcoat 5 is moved in adapter sleeve 3 lower arrow direction, make the groove of overcoat 5 inwall relative with two holes of adapter sleeve 3, lower spheres 4 as shown in Figure 4 falls into groove, like this, staking screw rod 1 can rotate relatively with adapter sleeve 3, thus unloads staking screw rod 1.
