Description

[0001] This utility model relates to a hand tool, specifically a handle (grip) for the tool. The utility model can be used in installation work involving suspended and fabric ceilings, as well as in construction, finishing, or gardening work, such as applying materials (putty, plaster, etc.) to surfaces and leveling them. For example, the utility model can be used for laying facing or floor tiles.

[0002] A hand tool with removable attachments (nozzles) that can be securely attached to a handle (handle) is known from the prior art. The handle has a first end and a second end with a longitudinal axis extending from the first end to the second end. A first mating surface is located at the first end. The handle includes a grip located near the proximal portion of the first mating surface. In a preferred embodiment, a threaded pin on the first mating surface and a wing nut are used as a fastening mechanism for attaching the first mating surface to a second mating surface of the removable device. Preferably, the handle also includes a stabilizing mechanism in the form of a locking pin and a stabilizing mechanism in the form of a recess for further stabilizing the removable device (patent for invention US 6,651,346 "Hand tool with interchangeable attachments", published on November 25, 2003).

[0003] The disadvantage of hand tools with interchangeable attachments is that the removable attachment is installed directly onto the first mating surface of the hand tool handle, without the use of additional spacers installed between them. As a result, during use, the first mating surface of the hand tool quickly wears out due to friction between the surface of the removable attachment and the first mating surface of the handle. Another disadvantage of hand tools with interchangeable attachments is that the recess in the side surface of the handle allows for additional fixation of only one end surface of the removable attachment, which will mate with the recess surface when the removable attachment and the handle are connected.

[0004] The technical problem with hand tools with interchangeable attachments is the reduced operational reliability of the tool as a whole. As a result, the service life of the tool with interchangeable attachments is reduced.

[0005] The technical result provided by the utility model consists in increasing the operational reliability and service life of the holding tool for replaceable attachments as a whole, achieved by the fact that the holding tool for replaceable attachments, made in the form of a handle, made with the possibility of connection with an element of the replaceable attachment by means of a fastening connection, on the side surface of the handle there is a recess, having an end side and a base, the recess is made of an elongated shape with two sides, in the base of the recess there is a through hole, in which an internal thread is made, and the fastening connection contains a threaded part.

[0006] The essence of the utility model is explained in Fig. 1-4.

[0007] Fig. 1 shows a holding tool for replaceable attachments, containing a handle.

[0008] Fig. 2 and 4 show holding tools for replaceable attachments, made in the form of a handle.

[0009] Fig. 3 shows replaceable attachments of different shapes with elements of replaceable attachments.

[0010] In Fig. 1-4 the following are indicated:

[0011] 1 - handle;

[0012] 2 - supporting element;

[0013] 3 - through hole;

[0014] 4 - overlay;

[0015] 5 - notch;

[0016] 6 - replaceable nozzle element;

[0017] 7 - end side of overlay 4;

[0018] 8 - side of overlay 4;

[0019] 9 - side of notch 5;

[0020] 10 - end side of recess 5;

[0021] 11 - end side of replaceable attachment element 6;

[0022] 12 - side of replaceable attachment element 6;

[0023] 13 - base of recess 5;

[0024] 14 - outer side of lining 4;

[0025] 15 - a hole made in the base 13 of the recess 5;

[0026] 16 - a protrusion made in the side 9 of the recess 5.

[0027] The utility model is made as follows.

[0028] The holding tool for the replaceable attachments is made in the form of a handle 1, configured to be connected to an element of the replaceable attachment 6, on the side surface of the handle there is a recess 5, having an end side 10 and a base 13. The recess 5 is made in an elongated shape with two side sides 9, and in the base 13 of the recess 5 there is an opening 15. Since the replaceable attachment 6 can consist of several elements connected to each other, therefore, the corresponding element of the replaceable attachment 6 will be connected to the holding tool made in the form of a handle 1.

[0029] To install the replaceable attachment element 6, it is necessary to place it in the recess 5 of the handle 1. Next, align the through hole made in the replaceable attachment element 6 with the hole 15 made in the base 13 of the recess 5, after which a fastening connection is placed in them, and with its help, fix the replaceable attachment element 6 in the holding tool made in the form of the handle 1.

[0030] In this case, such elements of replaceable attachments 6 are selected, the shape of which repeats the shape of the recess 5, and the dimensions of the elements of replaceable attachments 6 are selected in such a way that these dimensions are proportionate to the dimensions of the recess 5.

[0031] In order to replace a faulty element of the replaceable nozzle 6 or to change the element of the replaceable nozzle 6, it is necessary to remove the fastening connection, disconnect the element of the replaceable nozzle 6 from the recess 5, and then install the serviceable (or new) element of the replaceable nozzle 6 in the reverse order.

[0032] In the implementation of the utility model, the replaceable attachment element is installed directly into a recess formed in a holding tool shaped like a handle. Unlike the prototype, the sides of the replaceable attachment element, the end face of the replaceable attachment element, and the side of the replaceable attachment element mating with the base of the recess will rest against the sides of the recess, the end face of the recess, and the base of the recess, respectively. Thus, unlike the prototype, the play of the replaceable attachment element will be reduced, reducing its friction against the base of the recess and, accordingly, reducing abrasion of the base. This will increase the operational reliability of the holding tool shaped like a handle and extend its service life compared to the prototype.

[0033] The most technologically advanced design of a holding tool for replaceable attachments is achieved if the fastening connection in the patented device contains a threaded part.

[0034] The most technologically advanced design of a holding tool for replaceable bits is achieved if a through hole 15 is formed at the base of the recess 5 in the patented device. Furthermore, the most technologically advanced design of a holding tool for replaceable bits is achieved if the through hole 15 has an internal thread. Furthermore, the hole 15 can be blind and, for example, also have an internal thread.

[0035] The most technologically advanced design of a holding tool for replaceable attachments is achieved if the pad 4 in the recess 5 in the patented device is fixed without a gap.

[0036] A pilot batch of the utility model was produced, which underwent experimental work and confirmed its advantages.

[0037] An example of the implementation of the patented device is listed below.
