Description of drawings
Fig. 1 is main TV structure figure of the present utility model.
Fig. 2 is the internal structure schematic representation of Fig. 1.
Coding among the figure is respectively: 1 is handle, and 2 is disc cam, and 3 is groove, and 4 is the head of a nail, and 5 are the nail body, and 6 is shank, and 7 is the pin pin, and 8 is the pin cap, and 9 is the countersunk head groove, and 10 is expansion sleeve.
Embodiment
As shown in Figure 1, 2, originally be convenient to take out the formula positioning device, comprise handle 1, disc cam 2 and expandable nail, disc cam 2 is fixedly arranged at the bottom of handle 1, there is the groove 3 that Open Side Down at the middle part of disc cam 2, and expandable nail comprises the head of a nail 4 and nail body 5, and the head of a nail 4 is fixedly arranged at the top of nail body 5, on groove 3 side walls pin-and-hole is arranged, the head of a nail 4 is hinged in the groove 3 by pin-and-hole and pin.
As shown in Figure 1, the diameter of disc cam 2 increases in the counterclockwise direction gradually.
As required, pin comprises shank 6, pin pin 7 and pin cap 8, and the left part of shank 6 fixedly has pin pin 7, and the right part of shank 6 fixedly has pin cap 8, and there is U-shaped groove at the middle part of selling pin 7, and the external diameter of selling the external diameter of pin 7 and pin cap 8 is all greater than the internal diameter of pin-and-hole.
As preferably, the left and right two ends of the groove 3 of corresponding shank 6 positions have countersunk head groove 9 respectively, and pin pin 7 and pin cap 8 are set in the countersunk head groove 9.Pin pin 7 and pin cap 8 can be hidden in the countersunk head groove 9 like this, make people be difficult for scratch in use.
During use, expandable nail is inserted in the expansion sleeve 10, when needs are dismantled, stirring handle 1 clockwise rotates disc cam 2, disc cam 2 edges along the axle center vertical direction are attached on the upper-end surface of expansion sleeve 10 all the time, because disc cam 2 diameters increase in the counterclockwise direction gradually, then the axle center will raise gradually, drive the head of a nail 4 and move upward, thereby expandable nail is pulled out.
