Further, described lower cover is fixed in pin removal main body by the first screw, and respectively there is an offset at the U-lag edge of pin removal main body by upper and lower surface; Pin removal body openings direction end face respectively has a screwed hole by both sides, and this screwed hole mates with the first screw, for fixing lower cover.
Further, described first screw is ware type screw, for locking lower cover.
Further, the link position of described screw rod and pin removal main body is provided with pad.
Further, the centre position of described pad is provided with draw-in groove, and draw-in groove is stuck on screw rod.
Further, described draw-in groove is U-lag.
Further, described pin removal main body is provided with backing pin, and backing pin is pad backing pin.
Further, described backing pin is straight pin.
Further, described pin removal main body is provided with the second screw, and the second screw is spacer screw, and pad is connected with the second screw.
Further, described pin removal main body is provided with U-lag, and sliding shoe is placed in U-lag.
Further, described lower cover is a cuboid, and lower cover is provided with rectangular channel, and connecting screw is placed in rectangular channel, and this rectangular channel is used for passing through pin.
Adopt the Mute pin puller of technique scheme, owing to being provided with sliding shoe in described pin removal main body, sliding shoe can moving along in pin removal main body, sliding shoe is arranged in pin removal main body by lower cover, pin removal main body and sliding shoe are interspersed with screw rod, there is a hole end face upper position of pin removal main body, for passing screw rod, sliding shoe is provided with connecting screw, connecting screw is connected with pin through lower cover, pin is threaded pin to be pulled out, sliding shoe and lower cover are detachable, so this Mute pin puller noiselessness, friction, firmly economize, stable working, sliding shoe and lower cover are changed convenient, wide accommodation, be particularly suitable for precision optical machinery, pull out band internal thread pin when the assembling of mould and maintenance to use.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of Mute pin puller of the present invention.
Fig. 2 is the exploded view of Mute pin puller of the present invention.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
As shown in Figures 1 and 2, a kind of Mute pin puller, comprise pin removal main body 6, sliding shoe 5 is provided with in pin removal main body 6, sliding shoe 5 can along mobile in pin removal main body 6, sliding shoe 5 is arranged in pin removal main body 6 by lower cover 3, pin removal main body 6 and sliding shoe 5 are interspersed with screw rod 10, there is a hole end face upper position of pin removal main body 6, for passing screw rod 10, the end outer surface of screw rod 10 is provided with screw, for hexagon socket head cap screw, sliding shoe 5 is provided with connecting screw 4, connecting screw 4 is connected with pin 1 through lower cover 3, pin 1 is threaded pin to be pulled out, sliding shoe 5 is a cuboid, its two sides respectively there is one groove, can coordinate with U-lag 61 position of pin removal main body 6, there is a tapped through hole at one end center, can coordinate with screw rod 10, it has a T-shaped blind slot by other end upper surface, for coordinating with connecting screw 4, sliding shoe 5 and lower cover 3 are detachable, so can change easily.
Lower cover 3 is fixed in pin removal main body 6 by the first screw 2, and respectively there is an offset at the edge of pin removal main body 6 by upper and lower surface, pin removal main body 6 opening direction end face respectively there is a screwed hole by both sides, this screwed hole mates with the first screw 2, for fixing lower cover 3, first screw 2 is ware type screw, for locking lower cover 3, screw rod 10 is provided with pad 7 with the link position of pin removal main body 6, the centre position of pad 7 is provided with draw-in groove 71, draw-in groove 71 is stuck on screw rod 10, draw-in groove 71 is U-lag, pin removal main body 6 is provided with backing pin 9, backing pin 9 is pad backing pin, backing pin 9 is straight pin, pin removal main body 6 is provided with the second screw 8, second screw 8 is spacer screw, pad 7 is connected with the second screw 8, the quantity of pad 7 is three, thickness is different, body portion is cylindrical, pad 7 is provided with thin slice, thin slice establishes a hole in the outer part, rope can tie up in this hole, anti-pad 7 is lost, pin removal main body 6 is provided with U-lag 61, sliding shoe 5 is placed in U-lag 61, lower cover 3 is a cuboid, lower cover 3 is provided with rectangular channel 31, connecting screw 4 is placed in rectangular channel 31, this rectangular channel 31 is for passing through pin 1, respectively there is a through hole on its surface by both sides, there is the conical surface in through hole one side aperture, this through hole and the conical surface mate with the first screw 2.
