During straight state, handlebar right part is located above U-shaped packing ring, and another hand presses down on pressing plate, makes the rubber of pressing plate lower surface
Block presses downwards handlebar,
Then rotary handle bar drives lock nut rotation, because lock nut is threadedly coupled with lower bearing pin, lock nut
Rotation just move down the right part of handlebar, when right part and U-shaped washer contacts and the manual rotational handle of handlebar
When bar is relatively elaborate, the hand of pressing pressing plate is unclamped, pressing handlebar makes handlebar line centered on upper pin rotate to left down, made
Handlebar left end bottom and pressing plate upper surface, because the outline of the right part of handlebar surrounds the center line of upper pin certainly
Right upper portion is to left lower in the reducing globoidal structure gradually increased, as handlebar turns left, the right part of handlebar
Outline will be by the gradual clamping platen of U-shaped packing ring, several block rubbers that pressing plate lower surface is set will be further tight
The upper surface of arm is pressed, so as to which arm is fixed.The last Handheld Division pulled again with hand on elastic pressuring plate, drive elasticity pressure
Piece line centered on fastening bolt horizontally rotates, and when touching when upwarping portion of handlebar left end, carries elastic pressuring plate upwards, makes bullet
Property tabletting location hook tightly suppress the portion that upwarps of handlebar downwards, so can ensure that handlebar positioning is motionless.
Because U-shaped bead top is provided with identical and press fit deep-slotted chip breaker corresponding with reducing globoidal structure, this
One structure really handlebar lock stud in the case of motionless can will not move right and depart from U-shaped packing ring, so that pressing plate is firm
Ground presses arm, arm is kept integrative-structure with support frame, so as to play good security reliability.
Stiffener plate plays a part of strengthening bonding strength between front vertical plate, back vertical plate and support beam, it is ensured that positioning arm
Reliability.Tilt prop plays a part of strengthening bonding strength between pedal and support limit plate, it is ensured that support limit plate by
To the plumbness kept during weight with pedal.
In addition, in order to increase the intensity of arm, i.e. lifting capacity, two square steel tube side-by-sides can be welded as a whole.Certainly, this
Sample needs to increase the distance between front vertical plate and back vertical plate to place two square steel tubes.
In summary, the utility model is designed reasonably, simple in construction, each spare and accessory parts use the structure of separable assembled,
With with dress, there is certain lifting capacity, can move on construction ground, and install it is convenient and swift, especially for hanging
Arm, for the ease of carrying and depositing, it is frequently necessary to dismantle after use, manually detent mechanism is locked and dismantled, no
Only security reliability is strong, and quite convenient and swift.In a word, the utility model sufficiently lower the work of worker in road construction
Intensity, operating efficiency is improved, and it is more safe and reliable.

Touch and when manual rotational handle bar 30 is relatively elaborate, unclamp the hand of pressing pressing plate 35, pressing handlebar 30 makes handlebar more than 30
Line rotates to left down centered on bearing pin 33, makes the left end bottom of handlebar 30 and the upper surface of pressing plate 35, due to handlebar 30
The outline of right part from right upper portion to left lower is in the change diameter and arc surface knot that gradually increases around the center line of upper pin 33
Structure 39, as handlebar 30 turns left, the outline of the right part of handlebar 30 will gradually compress pressure by U-shaped packing ring 31
Plate 35, several block rubbers 41 that the lower surface of pressing plate 35 is set will further press the upper surface of arm 4, so as to by arm 4
It is fixed.The last Handheld Division 45 pulled again with hand on elastic pressuring plate 43, during driving elastic pressuring plate 43 is with fastening bolt 49
Heart line horizontally rotates, and when touching when upwarping portion 42 of the left end of handlebar 30, carries elastic pressuring plate 43 upwards, makes elastic pressuring plate 43
What location hook 44 tightly suppressed downwards handlebar 30 upwarps portion 42, and it is motionless so to can ensure that handlebar 30 positions.
Because the U-shaped top of packing ring 31 is provided with identical and press fit deep-slotted chip breaker corresponding with reducing globoidal structure 39
40, this structure really the lock stud in the case of motionless of handlebar 30 can will not move right and depart from U-shaped packing ring 31, so that
Pressing plate 35 securely presses arm 4, arm 4 is kept integrative-structure with support frame 1, so as to play good security reliability.
Stiffener plate 46 plays a part of strengthening bonding strength between front vertical plate 27, back vertical plate 28 and support beam 3, it is ensured that fixed
The reliability of position arm 4.Tilt prop 48 plays a part of strengthening bonding strength between pedal 47 and support limit plate 51, it is ensured that branch
Support limiting plate 51 is kept and the plumbness of pedal 47 when by weight.
In addition, in order to increase arm semi-finals degree, i.e. lifting capacity, two square steel tube side-by-sides can be welded as a whole.Certainly, this
Sample needs to increase the distance between front vertical plate 27 and back vertical plate 28 to place two square steel tubes.
The present embodiment not makees any formal limitation, every foundation to shape of the present utility model, material, structure etc.
Any simple modification, equivalent change and modification that the technical essence of the utility model is made to above example, belongs to this reality
With the protection domain of new technique scheme.
