The second receiving space and the first receiving space are preferably in a vertical state, so that the force transmission therebetween is more direct, and if the second receiving space and the first receiving space are in a non-vertical state, the force applied to the stopper 17 by the push rod 16 will be dispersed and lost for a part.
The contact surface between the push rod 16 and the stop lever 17 is also preferably set to be an inclined surface, and the inclined surface of the stop lever 17 is matched with the inclined surface, so that the action of force is more uniform, but it should be noted that the embodiment can still be realized even if the contact surface between the push rod 16 and the stop lever 17 is a right-angle surface.
Preferably, the present invention provides two embodiments of the second accommodating space.
The second accommodating space is horizontally arranged, and a spring is arranged in the gap. When the push rod 16 applies pushing force to the inclined surface of the stop lever 17 to push the stop lever 17 into the gap, the spring is extruded; when the push rod 16 is pulled out from the first accommodating space, the stop rod 17 receives the elastic force of the spring to make the contact end rebound to the first accommodating space, and the first accommodating space is divided into a first secondary space and a second secondary space again. The blocking lever 17 is pushed into the gap by the push rod 16 and is sprung out as a movement cycle of the blocking lever 17, which movement affects the possibility of removing the special screwdriver 9: when the stop lever 17 is not pushed into the gap, the special-shaped screwdriver 9 can not be taken out; after the stop rod 17 is pushed into the gap, the special screwdriver 9 can be taken out.
The second accommodating space is perpendicular to the ground, and when the push rod 16 is pulled out from the first accommodating space, the stop rod 17 falls into the first accommodating space due to gravity, so that the first accommodating space is divided into a first secondary space and a second secondary space. Compared with the second accommodating space which is horizontally arranged, the second accommodating space which is vertically arranged can save the structure of a spring, and the stop rod 17 returns to the first accommodating space again by directly using gravity and divides the first accommodating space into a first secondary space and a second secondary space, so that a movement period is realized.
Preferably, in order to prevent the operator from pushing out the special-shaped screwdriver 9 by using other tools, the first magnet block is arranged in the gap and is in contact with the movable end of the stop rod 17 to block the movement of the stop rod. And a second magnet block is arranged in the one-way bearing 8 at a position corresponding to the first magnet block, an axial third accommodating space is also arranged in the side plate, one end of the third accommodating space is closed, and the other end of the third accommodating space is communicated with a gap of the second accommodating space. Only when the one-way bearing 8 is sleeved on the screw rod 7, the one-way bearing 8 moves along the axial direction of the screw rod to enable the second magnet block and the first magnet block to repel or attract each other, the first magnet block can be repelled or attracted into the third accommodating space, the gap is vacated to allow the stop lever 17 to move, at the moment, the push rod 16 applies thrust to the inclined plane of the stop lever 17 to enable the stop lever 17 to be pushed into the gap, the two secondary spaces are communicated, and the push rod 16 can be continuously used for pushing the special-shaped screwdriver 9 out.
The contact surface between the first magnet block and the blocking rod 17 and the contact surface between the blocking rod 17 and the first magnet block are inclined surfaces, and the first magnet block and the blocking rod 17 are matched with each other, so that the blocking rod 17 can smoothly support the first magnet block into the third accommodating space after applying force to the first magnet block.
The third receiving space and the second receiving space are preferably in a vertical state, so that the force transmission therebetween is more direct, and if the third receiving space and the second receiving space are in a non-vertical state, the force applied to the first magnet block by the blocking rod 17 is dispersed and lost for a part, but it should be noted that even if the third receiving space and the second receiving space are preferably in a non-vertical state, the embodiment can still be implemented.
It is worth to be noted that the third accommodating space may be set such that the closed end is close to the one-way bearing 8 or the closed end is far from the one-way bearing 8, when the closed end of the third accommodating space is close to the one-way bearing 8, the magnetic poles of the second magnet block and the first magnet block are opposite, so that when the one-way bearing 8 is sleeved on the lead screw 7, the second magnet block and the first magnet block are close to each other and then attracted to each other, so that the first magnet block is attracted into the third accommodating space; when the closed end of the third accommodating space is far away from the one-way bearing 8, the magnetic poles of the second magnet block and the first magnet block are communicated, so that when the one-way bearing 8 is sleeved on the screw 7, the second magnet block and the first magnet block are close to each other and then are repelled, and the first magnet block is repelled into the third accommodating space.
Preferably, a spring is arranged in the third accommodating space, and when the first magnet block is attracted or repelled into the third accommodating space, the spring is stressed and compressed; when the push rod 16 is pulled out from the first accommodating space, the first magnet is rebounded to the gap by the elastic force of the spring, so that the contact end of the stop rod 17 is rebounded to the first accommodating space, and the first accommodating space is divided into a first secondary space and a second secondary space.
It should be noted that the elastic force of the spring in the third accommodating space needs to be smaller than the magnetic force between the second magnet block and the first magnet block, so as to ensure that the spring can be compressed under the magnetic acting force of the spring.
Preferably, the outlet of the special-shaped screwdriver 9 in the first accommodating space is higher than the inlet of the push rod 16 in the first accommodating space; when the push rod 16 applies a pushing force to the special shaped screwdriver 9, the special shaped screwdriver 9 is lifted until reaching the outlet, so that the special shaped screwdriver 9 falls from the outlet.
Specifically, the first accommodating space may be configured as an upward inclined through channel, and when the push rod 16 applies a pushing force to the special-shaped screwdriver 9, the special-shaped screwdriver 9 may be directly pushed obliquely upward along the channel until it reaches the outlet. Another preferred way is that the outlet of the special-shaped screwdriver 9 from the first accommodating space is higher than the bottom surface of the first accommodating space, the outlet is perpendicular to the bottom surface of the first accommodating space, and when the push rod 16 applies a pushing force to the special-shaped screwdriver 9, the special-shaped screwdriver 9 needs to be lifted up to reach the height of the outlet and then be pushed out of the outlet.
Preferably, the placing hole is formed in the top of the side plate and communicated with the first accommodating space, the special-shaped screwdriver 9 is inserted into the placing hole and then falls into the first accommodating space, and the special-shaped screwdriver 9 is conveniently placed back into the proposed accommodating space after being maintained by an operator.
