Described handle and connecting rod assembly includes: handle, handle socket, handle socket flap, U template connecting rod, bull stick, bearing pin; Handle is connected on the handle socket by the tapped bore on the handle socket, handle socket and handle socket flap are by being welded to connect, the handle socket flap is connected by bearing pin with the slotted hole U template of U template connecting rod one end, and the slotted hole U template of the U template connecting rod other end connects to form the handle and connecting rod assembly by bearing pin and bull stick;

Described U template connecting rod includes: two on slotted hole U template, pipe link; Two slotted hole U templates are the upright position and are welded on pipe link two ends composition U template connecting rod.

Beneficial effect: owing to adopted such scheme, when handle (7) cw or when rotating counterclockwise, handle socket (8) and handle socket flap (9) thorny handle socket rotating shaft (2) are rotated, handle socket flap (9) drives U template connecting rod (10) crank motion by bearing pin (6), U template connecting rod (10) drives bull stick (11) conter clockwise by bearing pin (6) or clockwise rotates, U template (4) rotates with bull stick (11), U template (4) drives horizontal plate (5) crank motion by bearing pin (6), horizontal plate (5) drives lorry-mounted crane control link (14) crank motion, lorry-mounted crane control link (14) crank motion is handled multiway valve, has realized the control of loop wheel machine.Reached the purpose of this utility model.

Advantage: increase by the 3rd cover handle operation mechanism, not only can also can realize operation, the dependable performance of lorry-mounted crane at high level at the low level place; When the lorry-mounted crane operation, can realize multi-faceted manipulation, can enlarge operator's field range, the situation of manipulation space deficiency in the time of having overcome operation again; This operating mechanism is applicable to the installation of the straight-arm lorry-mounted crane of a plurality of tonnages commonly used; It is less that this operating mechanism takies the space of whole loop wheel machine, can get off at existing finished product lorry-mounted crane and handle direct mount; It is lower to increase the required cost of this operating mechanism, and simple installation has better practicability.
