Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.
A kind of drawing horse as shown in Figure 1 to 4, including pushing tow screw rod 1, the top of pushing tow screw rod 1 is six for being coaxially disposed
Side shape post 2, bottom is nose cone 3, and connecting seat 4 is threaded with pushing tow screw rod 1, and three companies are circumferentially evenly equipped with connecting seat 4
Connecting terminal 5,5 one-tenth of connection terminal is shaft-like, and one end is connected with connecting seat 4, and the other end stretches out back to the axis of pushing tow screw rod 1,
The free end of each connection terminal 5 is respectively arranged with one and not only axially but also perpendicular to connection terminal 5 extends perpendicular to pushing tow screw rod 1
The pin-and-hole 6 in direction, the distance in the center of each pin-and-hole 6 to the axle center of pushing tow screw rod 1 is equal, and the free end of each pushing tow screw rod 1 passes through respectively
The articulated pulling claw 8 of the first bolt 7 in insertion pin-and-hole 6, pulling claw 8 is near one end of nose cone 3 to the central shaft of pushing tow screw rod 1
It is bent to form drag hook 9, it is characterised in that a standby connection terminal 10 is also associated with the connecting seat 4, the standby connection end
Son 10 is symmetrical arranged with three connection terminals 5 relative to pushing tow screw rod 1, and the free end of standby connection terminal 10 is same
One is provided with not only perpendicular to pushing tow screw rod 1 axially but also perpendicular to the standby pin-and-hole 11 of the bearing of trend of standby connection terminal 10, it is standby
Distance with pin-and-hole 11 to the axle center of pushing tow screw rod 1 is equal with the distance of pin-and-hole 6 to the axle center of pushing tow screw rod 1.
Two pulling claws 8 adjacent with standby connection terminal 10 are pulled down, one of pulling claw 8 is then installed to standby connection
On terminal 10, it is formed two pawls and draws horse, thus can both realize that two pawls drew the function of horse, the function of Three-claw pull-horse is realized again
.
The pulling claw 8 includes mobile jib 8-1, and mobile jib 8-1 middle parts are provided perpendicular to the second pin-and-hole 8-2 of mobile jib 8-1 axial directions,
The second bolt 8-3 is provided with second pin-and-hole 8-2, mobile jib 8-1 both sides are rotatably connected to a piece of connecting plate 8-4, the company respectively
The two ends of fishplate bar 8-4 are respectively arranged with a through hole, and same one end of two panels connecting plate 8-4 is by the second bolt 8-3 and mobile jib 8-1
It is connected, the other end of two panels connecting plate 8-4 is rotatably connected on a both sides for connection terminal 5 by first bolt 7 respectively,
The lower end of mobile jib 8-1 is hinged with an arc secondary bar 8-6 bent to the direction of pushing tow screw rod 1 by bearing pin 12, under secondary bar 8-6
It is drag hook 9 to hold, and the bearing pin 12 is parallel with the second bolt 8-3.
Rotatable connecting plate 8-4 can expand the use scope for drawing horse, when connecting plate 8-4 is rotated up around the first bolt,
Then so that mobile jib 8-1 is away from pushing tow screw rod 1, the extending range between each pulling claw 8 is bigger.
The upper end of the mobile jib 8-1 sets the inclined rod handle 8-5 in the oriented direction away from pushing tow screw rod 1.
Rod handle 8-5 is inclined to the direction away from pushing tow screw rod 1, is conducive to operator to exert a force, and operator can easily hold
The rod handle 8-5 of each pulling claw, then gathers to center, extends each pulling claw 8.
The rod handle 8-5 is along the thickness of the second bolt 8-3 axial directions more than mobile jib 8-1 along the second bolt 8-3 axial directions
Thickness, rod handle 8-5 and the smooth contact area docked, increase operator's finger and rod handle 8-5 of mobile jib 8-1 circular arcs, in order to grasp
Author captures,.
Operation principle of the present utility model is：As shown in Fig. 2 when needing to use two pawls to draw horse, pulling down and standby connection
, then be installed to one of pulling claw 8 on standby connection terminal 10 by two adjacent pulling claws 8 of terminal 10, is formed two pawls
Horse is drawn, when Three-claw pull-horse is needed to use, recovers as former state just, thus can both realize that two pawls drew the function of horse, realized again
The function of Three-claw pull-horse.
