The card slot 19 of interference fit.When people move up mobile bar 13, support rod 16 is rotated directly to the side far from support slot 15
It is in a vertical state to support rod 16, pulling block 14 is unclamped again, so that support rod 16 is located in limiting slot 17.Support rod 16 plays branch
The effect of pulling block 14 is supportted, so that people are when being inserted into connecting rod 5 without persistently pulling pulling block 14.When people do not use support rod 16
When, support rod 16 is embedded in corresponding support slot 15, fixture block 18 and the interference fit of card slot 19 play fixed support rod 16
Effect, avoid support rod 16 arbitrarily mobile.
As shown in Figure 1, Figure 3, the front end face of second clamping plate 4 is equipped with the fixing groove 20 of annular, is slidably equipped with ring in fixing groove 20
The fixed block 21 of shape, the cross section of fixed block 21 are in dovetail shaped.The front end face of fixed block 21 is fixed with fixed ring 22, fixed ring 22
Inner wall on be circumferentially evenly equipped with two sliding shoes 23.The upper and lower end face of connecting rod 5 is equipped with a sliding groove 24, and sliding groove 24
In the front end of connecting rod 5, two sliding shoes 23 are slidably installed in respectively in two sliding grooves 24.The outer wall of connecting rod 5 is equipped with annular
Slot 25.During connecting rod 5 passes through connecting hole 8, sliding shoe 23 is moved along corresponding sliding groove 24, works as first clamping plate
3 and second clamping plate 4 when clamping iron yoke 2, the position of sliding shoe 23 and annular groove 25 is corresponding, and people can be made by rotating fixed ring 22
Sliding shoe 23 and sliding groove 24 separate, and sliding shoe 23 is limited by annular groove 25 at this time cannot continue to move along sliding groove 24,
To play the role of further fixing first clamping plate 3 and second clamping plate 4, when improving first clamping plate 3 and the connection of second clamping plate 4
Stability.When fixed ring 22 rotates, fixed block 21 is rotated along fixing groove 20, and fixed block 21 and fixing groove 20 cooperate so that solid
Determining ring 22 will not separate with second clamping plate 4.
The working principle of the present embodiment: when the fixed iron yoke 2 of people, first passing through pulling block 14 moves up mobile bar 13,
Locating piece 6 moves up therewith and squeezes retaining spring 7, then rotates support rod 16 to the side far from support slot 15 and makes two
Support rod 16 is respectively embedded into corresponding limiting slot 17.Then connecting rod 5 is connected to close to the movement of the side of connecting hole 8
Second inclined-plane 11 during passing through locating slot 9 of extension bar 5 is mutually abutted with the first inclined-plane 10, and connecting rod 5 generates locating piece 6
Upward active force, locating piece 6 move up and the deformation of retaining spring 7 are made to generate elastic force, and locating piece 6 is under the action of retaining spring 7
Clamp connecting rod 5.When first clamping plate 3 and second clamping plate 4 are abutted with iron yoke 2, the position pair of sliding shoe 23 and annular groove 25
It answers, separates sliding shoe 23 with sliding groove 24 finally by rotation fixed ring 22, the side wall of annular groove 25 makes sliding shoe 23 not
It will continue to move along sliding groove 24, so that first clamping plate 3 and second clamping plate 4 be avoided to relatively move, improve first clamping plate 3
Stability when being connected with second clamping plate 4.People can connect first clamping plate 3 and second clamping plate 4 without tools such as spanners,
With the function convenient for the fixed iron yoke 2 of people.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
