[0007] Furthermore, in order to enable the top head to lift equipment at different angles, the top plate assembly includes: a top plate, a spherical sleeve, and a rubber pad. The top of the top head is configured as a spherical structure. The spherical sleeve is embedded in the spherical structure of the top of the top head and forms a spherical universal joint structure with the top head. The top of the spherical sleeve is provided with a top plate with a flat structure.

[0008] Furthermore, in order to provide good anti-skid capability for the top of the top plate when the top plate is tilted, the top of the top plate is covered with a rubber pad, and the top surface of the rubber pad is provided with a mesh anti-skid pattern.

[0009] Furthermore, in order to provide the jack with an extended lever arm when it is raised or lowered, and to save effort when prying up the jack, a pressure rod with a tubular or rod-shaped structure is embedded and fixed in the rod sleeve.

[0010] Furthermore, in order to facilitate the pushing and pulling operations of the jack when the jack is moved, a handle is vertically connected to both sides of one end of the pressure rod away from the rod sleeve.

[0024] A mobile and flexible jack, comprising: a jack 1, a pressure piston rod 4; a top 2 is the lifting end of the jack 1 (the matching mode and working principle of the top 2, the jack 1, and the pressure piston rod 4 are common matching modes in the prior art, so the specific matching mode and principle are omitted, and the specific structure can be referred to CN2054450U), both sides of the jack 1 use the pressure piston rod 4 to provide the lifting power of the top 2, and the top of the pressure piston rod 4 is hinged with an articulated sleeve 6, with a total of two sets of articulated sleeves A sleeve 6 is rotatably fitted with a connecting rod 5 on the hinged sleeve 6, and the other end of the connecting rod 5 is hinged to the bottom of the jack 1. A movable rod 7 of a tubular structure is embedded and fixed in each set of hinged sleeves 6. The two sets of movable rods 7 are parallel to each other, and the ends of the two sets of movable rods 7 close to the pressure piston rod 4 are bent close to each other and fixed together on a sleeve structure rod sleeve 9, and a walking wheel 8 is fixed to the lower part of the two sets of movable rods 7 close to the connecting rod 5. A top plate assembly 3 that can flexibly change the jacking angle is provided on the top of the jack 2.

[0025] The portion where the movable rod 7 is connected to the traveling wheel 8 is provided with a downward boss to form a wheel seat 71 . The bottom surface of the wheel seat 71 is planarized, and the traveling wheel 8 is fixed to the wheel seat 71 with bolts.

[0026] The top plate assembly 3 includes: a top plate 31, a spherical sleeve 32, and a rubber pad 33. The top of the plug 2 is set to a spherical structure. The spherical sleeve 32 is embedded in the spherical structure of the top of the plug 2 and forms a spherical universal joint structure with the plug 2. The top of the spherical sleeve 32 is provided with a top plate 31 with a flat structure.

[0027] The top of the top plate 31 is covered with a rubber pad 33 , and the top surface of the rubber pad 33 is provided with a mesh anti-skid pattern.

[0028] A compression rod 10 with a tubular or rod-shaped structure is embedded and fixed in the rod sleeve 9 .

[0029] A handle 11 is vertically connected to both sides of one end of the pressure rod 10 away from the rod sleeve 9 .

[0030] The part of the jack 1 that slides with the pressure piston rod 4 is a piston rod sleeve 12. The piston rod sleeve 12 is provided with a threaded hole that penetrates into the interior thereof. The threaded hole is threaded with a fixing bolt 13. After tightening, the inner end of the fixing bolt 13 is pressed against the outer wall of the pressure piston rod 4.
