[0021] Hereinafter, embodiments of the multifunctional boosting rod of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4The multifunctional boosting rod of an embodiment of the present invention is shown, comprising a boosting rod 2 inserted into the inner cavity of a long sleeve 1, the top and bottom of the surface of the boosting rod 2 are both provided with anti-skid pads 7, the anti-skid pads 7 are rubber sleeves, a short sleeve 8 is fixedly connected to the right side of the long sleeve 1, the short sleeve 8 is adapted to the pry head 5, the inner walls of the long sleeve 1 and the short sleeve 8 are bonded with buffer pads 9, and the setting of the buffer pads 9 protects the inner walls of the long sleeve 1 and the short sleeve 8, so that when the vehicle is driving, the boosting rod 2 and the pry head 5 will not generate large noise when shaking, a sleeve 3 is welded to the bottom of the boosting rod 2, a plug 4 is welded to the top of the boosting rod 2, a pry head 5 is provided above the boosting rod 2, and a docking assembly 6 is provided at the bottom of the pry head 5, the docking assembly 6 includes a connecting sleeve 61 fixedly connected to the bottom of the pry head 5, the connecting sleeve 61 The surface of the plug 4 is provided with a plurality of through holes 62 in an annular manner, and the inner cavity of the through holes 62 is embedded with a slidable ball 63. The bottom of the surface of the plug 4 is fixedly connected with a positioning sleeve 64, which is inserted into the inner cavity of the connecting sleeve 61, and the ball 63 is engaged with the surface of the positioning sleeve 64. The surface of the connecting sleeve 61 is provided with a slidable limiting sleeve 65, and the surface of the connecting sleeve 61 is provided with a spring 66. The top and bottom ends of the spring 66 are respectively welded to the connecting sleeve 61 and the limiting sleeve 65. Through the setting of the spring 66, the limiting sleeve 65 is elastically promoted, so that the limiting sleeve 65 can actively move downward, squeezing the ball 63, so that the ball 63 is stably engaged with the surface of the positioning sleeve 64, and the connecting sleeve 61 is limited and locked, so that the pry head 5 can be stably sleeved on the surface of the plug 4.

[0023] Working principle: When the utility model is used, the user fixes the long sleeve 1 and the short sleeve 8 on the oil pump vehicle by screws, stores the booster rod 2 and the pry head 5, and when in use, the plug 4 can be inserted into the end of the wrench for disassembling and installing the vehicle tire to increase the force and twist it, or the sleeve 3 can be placed on the pressure rod of the hydraulic cylinder to increase the force and press it. When it is necessary to pry the oil well cover, the user puts the connecting sleeve 61 on the surface of the plug 4, and then moves the limit sleeve 65 upwards, which causes the limit sleeve 65 to cause the spring 66 to The user squeezes and then presses down the pry head 5 so that the pry head 5 is sleeved on the surface of the plug 4, and at the same time, the connecting sleeve 61 is sleeved on the surface of the positioning sleeve 64. The user then releases the limiting sleeve 65. At this time, the spring 66 rebounds and pushes the limiting sleeve 65 downward to slide. The limiting sleeve 65 squeezes the ball 63 during the sliding process, so that the ball 63 is engaged with the surface of the positioning sleeve 64, connecting and fixing the pry head 5 and the plug 4. Finally, the user inserts the pry head 5 into the hole of the manhole cover and pries the manhole cover.

[0024] To sum up, the multifunctional booster rod, through the coordinated use of the long sleeve 1 and the short sleeve 8, can place the booster rod 2 and the pry head 5 in the vehicle position and take them out when needed. At the same time, with the coordinated use of the sleeve 3, the plug 4 and the pry head 5, the booster rod can be used to disassemble and assemble the tires, press the well bracket and pry the manhole cover, thereby achieving the purpose of easy disassembly and assembly, ready use and multifunctional use.
