Description

 Driver drive structure  

The present invention relates to a sub-driver structure, and more particularly to a nip portion of a latch member in a driver drive structure that includes a plurality of snap-in teeth that mesh with more teeth between the drive members.

As previously known to us, the conventional driver-driven structure is also a patent application filed by us, as shown in U.S. Patent No. US9278435B2, which is based on a fixed seat 10 on the front side of the mount 10. The first slot 111 and the second slot 113 are disposed on the bottom of the slot, and the first slot 111 is provided with a first pivot hole. A second pivot hole 114 is defined in the bottom of the second slot 113. The first pivot hole 112 and the second pivot hole 114 are through holes. The bottom of the slot 11 is connected to the fixing base 10. a rear side of the fixing seat 10 is provided with a receiving groove 13 on the rear side of the fixing base 10, and two fixing posts 14 and four fixing grooves 15 are disposed on the front end surface of the fixing base 10, and A peripheral surface of the fixing base 10 has a projection 16 on a side opposite to the receiving groove 13; a driving rod 20 having a large outer diameter ratchet portion 21, the ratchet portion 21 The toothed portion 21 includes a plurality of convex teeth and a tooth groove disposed therebetween, and the driving portion 21 is oppositely disposed. The rear side of the 20 is provided with a shaft portion 22 having a smaller outer diameter. The shaft portion 22 is rotatably disposed in the through hole 12, and a buckle groove 23 is formed on the rear surface of the shaft portion 22, and the buckle The slot 23 is exposed outside the fixing base 10. The front end of the driving rod 20 is provided with an active end 24, which is a polygonal slot for inserting into a screw, a sleeve or a post. A ring groove 25 is disposed on the peripheral surface of the driving rod 20, and a four-clamping member 30 is disposed on the two first slots 111 and the second In the two slots 113, the lower side and the upper side of one end of each of the latching members 30 respectively protrude from the pivot post 31 and an upper pivot post 32, and the latching member 30 in the first slot 111 The lower pivot post 31 is rotatably inserted into the first pivot hole 112, so that the latching member 30 can be swung to the other end portion to be engaged in the tooth groove of the ratchet portion 21, and further the fixing The base 10 can drive the drive rod 20 to reverse through the latching member 30 in the first slot 111. The lower pivot post 31 of the latching member 30 in the second slot 113 is rotatably inserted in the second pivot hole. 114, so that the card member 30 can swing So that the other end portion is locked in the tooth groove of the ratchet portion 21, and further, the fixing base 10 can drive the driving rod 20 to pass through the latching member 30 in the second slot 113; the four-click spring The four latching springs 40 are respectively disposed in the two first slots 111 and the two second slots 113. One end of the latching spring 40 in the first slot 111 is abutted against the slot of the first slot 111. On the wall, the other end is abutted against one side of the corresponding latching member 30, and one end of the latching spring 40 in the second slot 113 is abutted against the slot wall of the second slot 113, and the other end is fastened. On the side of one of the corresponding latching members 30, the four latching members 30 are respectively swung by the elastic force of the four latching springs 40 so that the other end portion is engaged in the slot of the ratchet portion 21 In a state, when the driving rod 20 rotates counterclockwise with respect to the fixing base 10, the plurality of protruding teeth of the ratchet portion 21 can push the latching member 30 in the first slot 111 to swing to compress the inner side of the latch The spring 40 forms an idling. When the driving rod 20 rotates clockwise relative to the fixing base 10, the plurality of protruding teeth of the ratchet portion 21 can push the latching member 30 in the second slot 113 to swing. The retaining plate 50 is coupled to the front end surface of the fixing base 10, and the four third pivot holes 51 are respectively provided for the four latching members 30. The upper pivot post 32 is rotatably inserted therein, and the two sets of the holes 52 are disposed in the periphery of the fixing plate 50 and are respectively embedded in the fixing plate 50 The control cover 60 is axially rotatably sleeved on the fixing base 10, and the front end surface has a uniform through hole 61 for the driving rod 20 to pass through. The control cover 60 is provided. The inside of the control cover 60 has three positioning slots 63 and a limiting slot 64. The limiting slot 64 is provided on the inner wall surface of the control cover 60. The bumps 16 are moved therein. When the bumps 16 are at one end of the limiting slots 64, the two control pieces 62 just separate the other ends of the two latching members 30 of the two first slots 111 from the spines. The two control pieces 62 can just make the two latching members 30 of the two second slots 113 another when the bump 16 abuts the other end of the limiting slot 64. The positioning portion is disposed in the receiving groove 13 , and the positioning spring 70 is disposed in the receiving groove 13 , and the positioning spring 70 is disposed in the receiving groove 13 The 71-type projectile is abutted between the accommodating groove 13 and the positioning bead 70, and the positioning bead 70 can be ejected outwardly so as to be correspondingly embedded in any one of the three positioning grooves 63 to control the cover. The 60 is respectively positioned at a position where the drive rod 20 can be idling counterclockwise, cannot be idling, and can be idling clockwise.

But the lack of the patent structure lies in:

1. Please attach the lower side and the upper side of one end of each of the latching members 30 to the pivot post 31 and an upper pivot post 32 respectively, as shown in the first and eighth figures of the bulletin. The lower pivot post 31 of the latching member 30 of the slot 111 is pivotally disposed in the first pivot hole 112 to enable the latching member 30 to swing to the other end portion of the ratchet portion 21. In any of the slots, the lower pivot post 31 of the latching member 30 in the second slot 113 is pivotally disposed in the second pivot hole 114, so that the latching member 30 can swing to the other end card. In any of the slots of the ratchet portion 21, each of the latching members 30 is in the form of a sheet, that is, each latching member 30 can only engage with one of the slots of the ratcheting portion 21, Insufficient torque due to insufficient meshing teeth.

The latching member 30 is in the form of a single body. The pivoting member 31 is disposed in the second pivot hole 114 and is received in the second pivot hole 114. The lower pivot post 31 of the latching member 30 in the slot 111 is pivotally disposed in the first pivot hole 112. The lower pivot post 31 is in the form of a circular body and the first pivot hole 112 in the shape of a circular hole or When the second pivot hole 114 is pivoted, the pivoted structure between the two is relatively inaccurate.

In view of the above-mentioned lack of the conventional driver drive structure, the inventors have years of experience in manufacturing and designing related industries, and finally have a product that can solve the drawbacks of the driver-driven structure.

The problem to be solved by the invention is that each of the latch members in the conventional driver drive structure can only engage with one of the slots of the ratchet portion, and the number of meshing teeth is insufficient to cause a lack of torque, and the driver of the present invention is driven.
