Detailed Description

Examples, see fig. 1-5: a standing push trowel includes a blade holder 10 and a blade 20 having an upper side fixed to a lower side of the blade holder 10. In this embodiment, the blade holder 10 and the blade 20 are each in the form of a square.

Further speaking:

the stand-up push trowel also includes a handle 30, the lower end of the handle 30 being connected to the blade carrier 10. That is, the operator can use the standing posture, and it is convenient to operate the blade 20 by the hand lever 30.

Optimizing:

the lower front surface of the blade holder 10 is provided with 2 ribs 11 extending in the left-right direction and parallel to each other. The ribs 11 are each projected forward, so that a single-row groove 12 is formed between 2 ribs 11. The cross section of the reinforcing rib 11 can be in a 7 shape. Meanwhile, the blade 20 is fixedly connected to the blade holder 10 by a fixing bolt 50, and a large end or a nut of the fixing bolt 50 is caught between the 2 reinforcing bars 11, so that the corresponding screw or nut does not rotate when rotated. That is, the large end or the nut of the fixing bolt 50 is caught in the bar-shaped groove 12 between the 2 reinforcing bars 11. Thus, the reinforcing ribs 11 not only have the effect of increasing the strength of the tool rest 10, but also have the function of positioning grooves, so that the assembly is simpler.

The lower portion of the handle bar 30 is connected to the tool holder 10 by a connecting member. This connecting piece includes: a connecting plate 41 with a rear side surface attached to the front side surface of the tool holder 10 and fixedly connected to the tool holder 10, and a connecting rod 42 fixed to the lower end portion of the hand lever 30. Meanwhile, a connecting lug 411 protruding forward is disposed on the front side of the connecting plate 41, and a left tooth form 412 annularly disposed on the left side of the connecting lug 411. The right side surface of the lower end of the connecting rod 42 is provided with a right tooth shape 421 which is distributed in a ring shape. And, after a connecting bolt 43 passes through the lower end of the connecting rod 42 and the connecting tab 411, the lower end of the connecting rod 42 and the connecting tab 411 are hinged together, and the left tooth form 412 and the right tooth form 421 are engaged with each other. Obviously, the center of the left tooth form 412 and the center of the right tooth form 421 both fall on the connecting bolt 43. Thus, the left tooth 412 and the right tooth 421, which snap together after only tightening the connecting bolt 43, ensure that the hand lever 30 has an adjustable angle of 0-180 relative to the tool holder 10, as shown in FIG. 6, for better use of the push trowel.

And (4) continuing optimization:

a cylindrical positioning pit 413 is arranged on the left side surface of the connecting lug piece 411; a cylindrical positioning column 422 is arranged on the right side surface of the lower end of the connecting rod 42. The positioning post 422 is engaged in the positioning hole 413, and the axial line of the positioning hole 413, the axial line of the positioning post 422, and the axial line of the connecting bolt 43 are overlapped. Thus, the connection between the connection tab 411 and the connection rod 42 is more stable and less prone to shake.

The lower end of the connecting rod 42 has an arc head 423, the connecting plate 41 is provided with an arc groove 414 at the left side of the connecting lug 411, and the arc head 423 is matched with the arc groove 414. That is, the axes of the arc-shaped head 423 and the arc-shaped groove 414 are coincident and have the same arc, so that the arc-shaped head 423 and the arc-shaped groove 414 are always attached to each other when the connecting rod 42 rotates relative to the connecting tab 411. In this way, stable connection of the connecting plate 41 and the connecting rod 42 is further ensured.

The lower end of the hand lever 30 has a conical screw thread (not shown), and the upper portion of the connecting rod 42 has a conical screw hole (not shown) opened upward, the conical screw thread and the conical screw hole being matched. That is, the hand lever 30 and the coupling lever 42 are coupled together after the conical screw and the conical screw hole are threadedly coupled, and the coupling becomes tighter as the degree of the threaded coupling is increased.

The upper side of the connecting plate 41 is bent backwards to form a positioning strip 415, the positioning strip 415 is attached to the upper side of the tool holder 10, and the lower side of the connecting plate 41 is attached to the reinforcing rib 11 located above the 2 reinforcing ribs 11. In this way, the connecting plate 41 is less susceptible to sliding than the tool holder 10, also with the aim of ensuring the stability of the connection between the parts.

The lower side of the tool holder 10 is an inclined surface 13 with the front side on the upper side and the rear side on the lower side. Therefore, residues are not easy to form during construction, and the residues on the blade 20 are convenient to clean.

In addition:

the lower part of the front side of the connecting plate 41 is provided with a convex rib 416 protruding forwards, and the convex rib 416 is connected with the root of the connecting lug 411; the upper part of the rear side of the blade holder 10 is provided with rearwardly extending auxiliary ribs 14. The purpose is to further reinforce the strength of the relevant components, especially the connecting tab 411.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
